SQL: Select Keys that doesn't exist in one table

Question

I got a table with a normal setup of auto inc. ids. Some of the rows have been deleted so the ID list could look something like this:

(1, 2, 3, 5, 8,

Answer 1

We can use MYSQL not in option.

SELECT id
FROM table_one
WHERE id NOT IN ( SELECT id FROM table_two )

Edited

If you are getting the source from a csv file then you can simply have to put these values directly like:

I am assuming that the CSV are like 1,2,3,...,n

SELECT id
FROM table_one
WHERE id NOT IN ( 1,2,3,...,n );

EDIT 2

Or If you want to select the other way around then you can use mysqlimport to import data in temporary table in MySQL Database and retrieve the result and delete the table.

Like:

Create table

CREATE TABLE my_temp_table(
   ids INT,
);

load .csv file

LOAD DATA LOCAL INFILE 'yourIDs.csv' INTO TABLE my_temp_table
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
(ids);

Selecting records

SELECT ids FROM my_temp_table
WHERE ids NOT IN ( SELECT id FROM table_one )

dropping table

DROP TABLE IF EXISTS my_temp_table
